The Pro Series, not the Performance Center.
The 640 Pro gets upgraded sights, a cylinder cut for moon clips, and (I believe) a trigger job.
The sights are a
big upgrade. You go from a pinned ramp front and U-cut frame rear, to a real front and rear sight--dovetail-fit Tritium night sights. It's a better sight, to start, and it makes the whole gun more interesting to shoot. Good sights don't just make it easier to hit, they make it more fun to practice with.
Not to mention--since they're dovetail-fit (super-rare in a small-frame revolver), they're
drift-adjustable! If you've got a decent sight pusher, you can adjust the sights on your J-frame!
The moon clip cut on the cylinder is pretty handy. It's not a cheap job to have done in the aftermarket--TK Custom will do the job for $150. It buys you not only easier reloads, but easier extraction. I would use .38 Spl +P to make extraction a cinch.
It also comes
sans lock. Begging the moderators' indulgence, I consider that a feature.
There are some other things (the Pro Series as has a fluted barrel that I wish they would not have done) but those are the two meaty upgrades.
The Pro Series MSRPs for $839. The base 640 goes for $729. Even just the moonclip cut makes the Pro a steal.
The last Bud's price for the Pro was $728 (they're out of stock), and their price for the base 640 is currently at $598. So--$130 bucks.
Lucky Gunner did an okay writeup:

And yes, at the end of the article, he says he's not giving up his LCR and thinks it's better. But that's okay, because he's wrong.
